Equal area projections usually preserve straight and perpendicular meridians and parallels. That’s neutral but then there’s the political decision of what latitude gets the correct aspect ratio. And Gall-Peters is not anti-colonialist if representing Africa correctly was your goal.
I don’t know what you mean by “other such variations”, but maybe you are looking for a map with something like the Mollweide projection? That’s a bit of distortion in shape but trying to keep areas real.
They want a 2d map of earth but with every continent to true size at scale, rather than Mercator projection where the northern hemisphere is expanded to increase their importance over the southern hemisphere.
Mercator wasn’t created in order to increase importance of the northern hemisphere, but to allow for directional rhumb lines to be drawn for shipping. For its intended purpose of navigation, it does an excellent job.
It may not be the intended purpose but I certainly does change how the world is seen by everyone using it to warp the mind’s eye to how the world actually physically is.
Edit: Does it do an excellent job for navigational purposes if you are shipping from Japan to Brazil or it it only excellent for shipping from the northern hemisphere to the northern hemisphere?
Perhaps if they are unaware that a 3D image of a geoid projected onto a 2D plane can cause issues, however every projection will have its own failings whether area, shape or directional (angular). Familiarity also comes into play, and i believe that is more at the root of the issue you bring up.
The Mercator projection was designed for use in marine navigation because of its unique property of representing any course of constant bearing as a straight segment. Such a course, known as a rhumb (alternately called a rhumb line or loxodrome) is preferred in marine navigation because ships can sail in a constant compass direction.
Anyone know of a 2D map print of true size? All I’ve found print wise is Mercator or other such variations.
Mathematically impossible, but you could try an Equal Area projection.

Essentially this. A true sized projection, it can be in any “cut” of the globe as long as all the continents are true to size.

No, because Africa is larger than Asia, and this shows Asia as massive.
You may want to double check that, or you probably will need an imaginary map.
Let me know if I understand correctly. You want a true to life sized map of earth? 😳

That’s not why Mercator exists
Exactl, this.

As for your navigational questions, this Reddit thread may be helpful https://www.reddit.com/r/explainlikeimfive/comments/4s4869/eli5_how_mercator_projections_are_better_for/
Do you seriously think that the geometrical properties of the projection change below the equator? You need to learn yourself some geometry.
It works for any shipping lines
